2 Product overview

2.1 EK1300 - Introduction

EtherCAT coupler EK1300

The EK1300 coupler integrates EtherCAT Terminals (ELxxxx) in the EtherCAT P network. The upperEtherCAT P interface is used to connect the coupler to the network, the lower EtherCAT-P-coded M8 socketis used for optional continuation of the EtherCAT P topology. Since EtherCAT P integrates the power supplyand the communication on a single line, an additional power supply for the coupler via the terminal points isno longer required. Depending on the application, the system and sensor supply US or the peripheral voltagefor actuators UP can be bridged to the power contacts. In addition to the Run LED and the link and activitystatus, status LEDs indicate the state of the US and UP voltages, as well as overload and short-circuit events.

2.2 EtherCAT PEtherCAT P combines communication and power in a single 4-wire standard Ethernet cable. The 24 V DCsupply of the EtherCAT P slaves and the connected sensors and actors is integrated within this bus system:US (system- and Sensor supply) and UP (peripheral voltage for actors) are electrical isolated with 3 A currentavailable for the connected components. All the benefits of EtherCAT, such as freedom in topology design,high speed, optimum bandwidth utilization, telegram processing on-the-fly, highly precise synchronization,extensive diagnostics functionality, etc. are all retained while integrating the voltages.

With EtherCAT P technology, the currents are coupled directly into the wires of the 100 Mbit line, enablingthe realization of a highly cost-effective and compact connection. In order to rule out the possibility ofincorrect connections to standard EtherCAT slaves and, thus possible defects, a new plug family has beenspecially developed for EtherCAT P. The plug family covers all applications from the 24 V I/O level up todrives with 400 V AC or 600 V DC and a current of up to 64 A.

EtherCAT P offers extensive savings potential:

• elimination of separate supply cables• low wiring effort and significant time savings• sources of error are reduced

Product overview

EK130012 Version: 1.0

• minimization of installation space for drag-chains and control cabinets• smaller and tidier cable trays• smaller sensors and actuators through the elimination of separate supply cables

As is typical with EtherCAT, the user benefits from the wide choice in topology and can combine line, starand tree architectures with one another in order to achieve the least expensive and best possible systemlayouts. Unlike the traditional Power over Ethernet (PoE), devices can also be cascaded using EtherCAT Pand supplied with power from one power supply unit.

When designing a machine, the individual consumers, cable lengths and cable types are configured with toolassistance and this information is used to create the optimum layout of the EtherCAT P network. Since it isknown what sensors and actuators will be connected and which ones will be operated simultaneously, thepower consumption can be accounted for accordingly. For example, if two actuators never switchsimultaneously from a logical point of view, they also never need the full load simultaneously. The result isfurther savings potential in terms of the required supplies and power supply units.

3 Basics communication

3.1 System properties

Protocol

The EtherCAT protocol is optimized for process data and is transported directly within the Ethernet framethanks to a special Ether-type. It may consist of several sub-telegrams, each serving a particular memoryarea of the logical process images that can be up to 4 gigabytes in size. The data sequence is independentof the physical order of the Ethernet terminals in the network; addressing can be in any order. Broadcast,Multicast and communication between slaves are possible. Transfer directly in the Ethernet frame is used incases where EtherCAT components are operated in the same subnet as the control computer.

However, EtherCAT applications are not limited to a subnet: EtherCAT UDP packs the EtherCAT protocolinto UDP/IP datagrams. This enables any control with Ethernet protocol stack to address EtherCAT systems.Even communication across routers into other subnets is possible. In this variant, system performanceobviously depends on the real-time characteristics of the control and its Ethernet protocol implementation.The response times of the EtherCAT network itself are hardly restricted at all: the UDP datagram only has tobe unpacked in the first station.

Fig. 9: EtherCAT Telegram Structure

Protocol structure: The process image allocation is freely configurable. Data are copied directly in the I/Oterminal to the desired location within the process image: no additional mapping is required. The availablelogical address space is with very large (4 GB).

Basics communication

EK130014 Version: 1.0

Topology

Line, tree or star: EtherCAT supports almost any topology. The bus or line structure known from thefieldbuses thus also becomes available for Ethernet. Particularly useful for system wiring is the combinationof line and junctions or stubs. The required interfaces exist on the couplers; no additional switches arerequired. Naturally, the classic switch-based Ethernet star topology can also be used.

Fig. 10: EtherCAT Topology

Maximum wiring flexibility:with or without switch, line or tree topologies, can be freely selected and combined.

Wiring flexibility is further maximized through the choice of different cables. Flexible and cost-effectivestandard Ethernet patch cables transfer the signals in Ethernet mode (100Base-TX). The completebandwidth of the Ethernet network - such as different optical fibers and copper cables - can be used incombination with switches or media converters.

Distributed Clocks

Accurate synchronization is particularly important in cases where spatially distributed processes requiresimultaneous actions. This may be the case, for example, in applications where several servo axes carry outcoordinated movements simultaneously.

The most powerful approach for synchronization is the accurate alignment of distributed clocks, as describedin the new IEEE 1588 standard. In contrast to fully synchronous communication, where synchronizationquality suffers immediately in the event of a communication fault, distributed aligned clocks have a highdegree of tolerance vis-à-vis possible fault-related delays within the communication system.

Basics communication

EK1300 15Version: 1.0

With EtherCAT, the data exchange is fully based on a pure hardware machine. Since the communicationutilizes a logical (and thanks to full-duplex Fast Ethernet also physical) ring structure, the mother clock candetermine the run-time offset to the individual daughter clocks simply and accurately - and vice versa. Thedistributed clocks are adjusted based on this value, which means that a very precise network-wide timebasewith a jitter of significantly less than 1 microsecond is available.

However, high-resolution distributed clocks are not only used for synchronization, but can also provideaccurate information about the local timing of the data acquisition. For example, controls frequently calculatevelocities from sequentially measured positions. Particularly with very short sampling times, even a smalltemporal jitter in the displacement measurement leads to large step changes in velocity. With EtherCAT new,extended data types are introduced as a logical extension (time stamp and oversampling data type). Thelocal time is linked to the measured value with a resolution of up to 10 ns, which is made possible by thelarge bandwidth offered by Ethernet. The accuracy of a velocity calculation then no longer depends on thejitter of the communication system. It is orders of magnitude better than that of measuring techniques basedon jitter-free communication.

Performance

EtherCAT reaches new dimensions in network performance. Protocol processing is purely hardware-basedthrough an FMMU chip in the terminal and DMA access to the network card of the master. It is thusindependent of protocol stack run-times, CPU performance and software implementation. The update timefor 1000 I/Os is only 30 µs - including terminal cycle time. Up to 1486 bytes of process data can beexchanged with a single Ethernet frame - this is equivalent to almost 12000 digital inputs and outputs. Thetransfer of this data quantity only takes 300 µs.

The communication with 100 servo axes only takes 100 µs. During this time, all axes are provided with setvalues and control data and report their actual position and status. Distributed clocks enable the axes to besynchronized with a deviation of significantly less than 1 microsecond.

The extremely high performance of the EtherCAT technology enables control concepts that could not berealized with classic fieldbus systems. For example, the Ethernet system can now not only deal with velocitycontrol, but also with the current control of distributed drives. The tremendous bandwidth enables statusinformation to be transferred with each data item. With EtherCAT, a communication technology is availablethat matches the superior computing power of modern Industrial PCs. The bus system is no longer thebottleneck of the control concept. Distributed I/Os are recorded faster than is possible with most local I/Ointerfaces. The EtherCAT technology principle is scalable and not bound to the baud rate of 100 Mbaud –extension to Gbit Ethernet is possible.

Diagnostics

Experience with fieldbus systems shows that availability and commissioning times crucially depend on thediagnostic capability. Only faults that are detected quickly and accurately and which can be precisely locatedcan be corrected quickly. Therefore, special attention was paid to exemplary diagnostic features during thedevelopment of EtherCAT.

During commissioning, the actual configuration of the I/O terminals should be checked for consistency withthe specified configuration. The topology should also match the saved configuration. Due to the built-intopology recognition down to the individual terminals, this verification can not only take place during systemstart-up, automatic reading in of the network is also possible (configuration upload).

Bit faults during the transfer are reliably detected through evaluation of the CRC checksum: The 32 bit CRCpolynomial has a minimum hamming distance of 4. Apart from breaking point detection and localization, theprotocol, physical transfer behavior and topology of the EtherCAT system enable individual qualitymonitoring of each individual transmission segment. The automatic evaluation of the associated errorcounters enables precise localization of critical network sections. Gradual or changing sources of error suchas EMC influences, defective push-in connectors or cable damage are detected and located, even if they donot yet overstrain the self-healing capacity of the network.

Integration of standard Bus Terminals from Beckhoff

In addition to the new Bus Terminals with E-Bus connection (ELxxxx), all Bus Terminals from the familiarstandard range with K-bus connection (KLxxxx) can be connected via the BK1120 or BK1250 Bus Coupler.This ensures compatibility and continuity with the existing Beckhoff Bus Terminal systems. Existinginvestments are protected.

3.2 EtherCAT basicsPlease refer to the chapter EtherCAT System Documentation for the EtherCAT fieldbus basics.

3.3 EtherCAT State MachineThe state of the EtherCAT slave is controlled via the EtherCAT State Machine (ESM). Depending upon thestate, different functions are accessible or executable in the EtherCAT slave. Specific commands must besent by the EtherCAT master to the device in each state, particularly during the bootup of the slave.

A distinction is made between the following states:

• Init• Pre-Operational• Safe-Operational and• Operational• Boot

The regular state of each EtherCAT slave after bootup is the OP state.

Fig. 11: States of the EtherCAT State Machine

Init

After switch-on the EtherCAT slave in the Init state. No mailbox or process data communication is possible.The EtherCAT master initializes sync manager channels 0 and 1 for mailbox communication.

Pre-Operational (Pre-Op)

During the transition between Init and Pre-Op the EtherCAT slave checks whether the mailbox was initializedcorrectly.

In Pre-Op state mailbox communication is possible, but not process data communication. The EtherCATmaster initializes the sync manager channels for process data (from sync manager channel 2), the FMMUchannels and, if the slave supports configurable mapping, PDO mapping or the sync manager PDOassignment. In this state the settings for the process data transfer and perhaps terminal-specific parametersthat may differ from the default settings are also transferred.

Basics communication

EK1300 17Version: 1.0

Safe-Operational (Safe-Op)

During transition between Pre-Op and Safe-Op the EtherCAT slave checks whether the sync managerchannels for process data communication and, if required, the distributed clocks settings are correct. Beforeit acknowledges the change of state, the EtherCAT slave copies current input data into the associated DP-RAM areas of the EtherCAT slave controller (ECSC).

In Safe-Op state mailbox and process data communication is possible, although the slave keeps its outputsin a safe state, while the input data are updated cyclically.

Note

Outputs in SAFEOP stateThe default set watchdog monitoring sets the outputs of the module in a safe state - de-pending on the settings in SAFEOP and OP - e.g. in OFF state. If this is prevented by de-activation of the watchdog monitoring in the module, the outputs can be switched or setalso in the SAFEOP state.

Operational (Op)

Before the EtherCAT master switches the EtherCAT slave from Safe-Op to Op it must transfer valid outputdata.

In the Op state the slave copies the output data of the masters to its outputs. Process data and mailboxcommunication is possible.

Boot

In the Boot state the slave firmware can be updated. The Boot state can only be reached via the Init state.

In the Boot state mailbox communication via the file access over EtherCAT (FoE) protocol is possible, but noother mailbox communication and no process data communication.

3.4 CoE - Interface: notesThis device has no CoE.

Detailed information on the CoE interface can be found in the EtherCAT system documentation on theBeckhoff website.

3.5 Distributed ClockThe distributed clock represents a local clock in the EtherCAT slave controller (ESC) with the followingcharacteristics:

• Unit 1 ns• Zero point 1.1.2000 00:00• Size 64 bit (sufficient for the next 584 years; however, some EtherCAT slaves only offer 32-bit support,

i.e. the variable overflows after approx. 4.2 seconds)• The EtherCAT master automatically synchronizes the local clock with the master clock in the EtherCAT

bus with a precision of < 100 ns.

For detailed information please refer to the EtherCAT system description.

3.6 EtherCAT P introduction

One cable solution for the field level

With EtherCAT P, Beckhoff combines communication and power in a single 4-wire standard Ethernet cable.The 24 V DC supply of the EtherCAT P slaves and of the connected sensors and actuators is integrated: US(system and sensor supply) and UP (peripheral voltage for actuators) are electrically isolated from eachother and can each supply a current of up to 3 A to the connected components. At the same time, all thebenefits of EtherCAT, such as: Cascadable in all topologies (star, line, tree), telegram processing on-the-fly,high data transfer rate 100 Mbit/s full duplex, optimum bandwidth utilization, highly precise synchronization,extensive diagnostics functionality, etc., are all retained.

The currents of US and UP are coupled directly into the wires of the 100 Mbit/s line, enabling the realisation ofa highly cost-effective and compact connection. EtherCAT P offers benefits both for connection of remote,smaller I/O stations in the terminal box and for decentralised I/O components locally in the process. Thefunction principle of the one cable solution for the field is shown in the following figure.

Fig. 12: From EtherCAT to EtherCAT P

The mechanical EtherCAT P coding (see figure below) was developed to prevent potential damage causedby incorrect connection with standard EtherCAT modules. The connector face consists of a centrally locatedT-piece and a nose and a triangle outside, also the 4 contacts are arranged symmetrically.

4 Mounting and wiring

4.1 Installation on mounting rails

WARNING

Risk of electric shock and damage of device!Bring the bus terminal system into a safe, powered down state before starting installation,disassembly or wiring of the Bus Terminals!

Assembly

Fig. 15: Attaching on mounting rail

The Bus Coupler and Bus Terminals are attached to commercially available 35 mm mounting rails (DIN railsaccording to EN 60715) by applying slight pressure:

1. First attach the Fieldbus Coupler to the mounting rail.2. The Bus Terminals are now attached on the right-hand side of the Fieldbus Coupler. Join the compo-

nents with tongue and groove and push the terminals against the mounting rail, until the lock clicksonto the mounting rail.If the Terminals are clipped onto the mounting rail first and then pushed together without tongue andgroove, the connection will not be operational! When correctly assembled, no significant gap shouldbe visible between the housings.

Note

Fixing of mounting railsThe locking mechanism of the terminals and couplers extends to the profile of the mountingrail. At the installation, the locking mechanism of the components must not come into con-flict with the fixing bolts of the mounting rail. To mount the mounting rails with a height of7.5 mm under the terminals and couplers, you should use flat mounting connections (e.g.countersunk screws or blind rivets).

Mounting and wiring

EK130022 Version: 1.0

Disassembly

Fig. 16: Disassembling of terminal

Each terminal is secured by a lock on the mounting rail, which must be released for disassembly:

1. Pull the terminal by its orange-colored lugs approximately 1 cm away from the mounting rail. In doingso for this terminal the mounting rail lock is released automatically and you can pull the terminal out ofthe bus terminal block easily without excessive force.

2. Grasp the released terminal with thumb and index finger simultaneous at the upper and lower groovedhousing surfaces and pull the terminal out of the bus terminal block.

Connections within a bus terminal block

The electric connections between the Bus Coupler and the Bus Terminals are automatically realized byjoining the components:

• The six spring contacts of the K-Bus/E-Bus deal with the transfer of the data and the supply of the BusTerminal electronics.

• The power contacts deal with the supply for the field electronics and thus represent a supply rail withinthe bus terminal block. The power contacts are supplied via terminals on the Bus Coupler (up to 24 V)or for higher voltages via power feed terminals.

Note

Power ContactsDuring the design of a bus terminal block, the pin assignment of the individual Bus Termi-nals must be taken account of, since some types (e.g. analog Bus Terminals or digital 4-channel Bus Terminals) do not or not fully loop through the power contacts. Power FeedTerminals (KL91xx, KL92xx or EL91xx, EL92xx) interrupt the power contacts and thus rep-resent the start of a new supply rail.

PE power contact

The power contact labeled PE can be used as a protective earth. For safety reasons this contact mates firstwhen plugging together, and can ground short-circuit currents of up to 125 A.

Mounting and wiring

EK1300 23Version: 1.0

Fig. 17: Power contact on left side

Attention

Possible damage of the deviceNote that, for reasons of electromagnetic compatibility, the PE contacts are capacitativelycoupled to the mounting rail. This may lead to incorrect results during insulation testing orto damage on the terminal (e.g. disruptive discharge to the PE line during insulation testingof a consumer with a nominal voltage of 230 V). For insulation testing, disconnect the PEsupply line at the Bus Coupler or the Power Feed Terminal! In order to decouple furtherfeed points for testing, these Power Feed Terminals can be released and pulled at least10 mm from the group of terminals.

WARNING

Risk of electric shock!The PE power contact must not be used for other potentials!

4.2 Installation instructions for enhanced mechanical loadcapacity

WARNING

Risk of injury through electric shock and damage to the device!Bring the Bus Terminal system into a safe, de-energized state before starting mounting,disassembly or wiring of the Bus Terminals!

Additional checks

Additional installation instructions

For terminals with enhanced mechanical load capacity, the following additional installation instructions apply:

• The enhanced mechanical load capacity is valid for all permissible installation positions• Use a mounting rail according to EN 60715 TH35-15• Fix the terminal segment on both sides of the mounting rail with a mechanical fixture, e.g. an earth

terminal or reinforced end clamp• The maximum total extension of the terminal segment (without coupler) is:

64 terminals (12 mm mounting with) or 32 terminals (24 mm mounting with)• Avoid deformation, twisting, crushing and bending of the mounting rail during edging and installation of

the rail• The mounting points of the mounting rail must be set at 5 cm intervals• Use countersunk head screws to fasten the mounting rail• The free length between the strain relief and the wire connection should be kept as short as possible. A

distance of approx. 10 cm should be maintained to the cable duct.

4.3 Installation positions

Attention

Constraints regarding installation position and operating temperature rangePlease refer to the technical data for a terminal to ascertain whether any restrictions re-garding the installation position and/or the operating temperature range have been speci-fied. When installing high power dissipation terminals ensure that an adequate spacing ismaintained between other components above and below the terminal in order to guaranteeadequate ventilation!

Optimum installation position (standard)

The optimum installation position requires the mounting rail to be installed horizontally and the connectionsurfaces of the EL/KL terminals to face forward (see Fig. “Recommended distances for standard installationposition”). The terminals are ventilated from below, which enables optimum cooling of the electronics throughconvection. "From below" is relative to the acceleration of gravity.

4.4 Connection system

WARNING

Risk of electric shock and damage of device!Bring the bus terminal system into a safe, powered down state before starting installation,disassembly or wiring of the Bus Terminals!

Overview

The Bus Terminal system offers different connection options for optimum adaptation to the respectiveapplication:

• The terminals of KLxxxx and ELxxxx series with standard wiring include electronics and connectionlevel in a single enclosure.

• The terminals of KSxxxx and ESxxxx series feature a pluggable connection level and enable steadywiring while replacing.

• The High Density Terminals (HD Terminals) include electronics and connection level in a singleenclosure and have advanced packaging density.

Standard wiring

Fig. 20: Standard wiring

The terminals of KLxxxx and ELxxxx series have been tried and tested for years.They feature integrated screwless spring force technology for fast and simple assembly.

Mounting and wiring

EK1300 27Version: 1.0

Pluggable wiring

Fig. 21: Pluggable wiring

The terminals of KSxxxx and ESxxxx series feature a pluggable connection level.The assembly and wiring procedure for the KS series is the same as for the KLxxxx and ELxxxx series.The KS/ES series terminals enable the complete wiring to be removed as a plug connector from the top ofthe housing for servicing.The lower section can be removed from the terminal block by pulling the unlocking tab. Insert the new component and plug in the connector with the wiring. This reduces the installation time andeliminates the risk of wires being mixed up.

The familiar dimensions of the terminal only had to be changed slightly. The new connector adds about 3mm. The maximum height of the terminal remains unchanged.

A tab for strain relief of the cable simplifies assembly in many applications and prevents tangling of individualconnection wires when the connector is removed.

Conductor cross sections between 0.08 mm2 and 2.5 mm2 can continue to be used with the proven springforce technology.

The overview and nomenclature of the product names for KSxxxx and ESxxxx series has been retained asknown from KLxxxx and ELxxxx series.

High Density Terminals (HD Terminals)

Fig. 22: High Density Terminals

The Bus Terminals from these series with 16 connection points are distinguished by a particularly compactdesign, as the packaging density is twice as large as that of the standard 12 mm Bus Terminals. Massiveconductors and conductors with a wire end sleeve can be inserted directly into the spring loaded terminalpoint without tools.

Note

Wiring HD TerminalsThe High Density (HD) Terminals of the KLx8xx and ELx8xx series doesn't support steadywiring.

Ultrasonically "bonded" (ultrasonically welded) conductors

Up to eight connections enable the connection of solid or finely stranded cables to the Bus Terminals. Theterminals are implemented in spring force technology. Connect the cables as follows:

1. Open a spring-loaded terminal by slightly pushing with a screwdriver or a rod into the square openingabove the terminal.

2. The wire can now be inserted into the round terminal opening without any force.3. The terminal closes automatically when the pressure is released, holding the wire securely and per-

manently.

5 CommissioningUse of US/ UP of the coupler

The outfeed of the coupler comes from the EtherCAT P signal input (X1). In addition, the coupler is poweredby this US voltage.

The connections for the supply of US/ UP can be used for the supply of the power contacts. To do this,jumpers from the output terminal points e.g. terminal point 1 and 5 for US or terminal point 4 and 8 for UP)must be placed on the infeed (terminal point 2/ 3 and 6/ 7). The bridges should be as short as possible.

As a result, the supply of the following terminals, which are fed from the power contacts realized. Usually, theinput modules are supplied from US and output modules from UP. If the outputs are to be switched offseparately, the outfeed UP of the coupler can be connected via a switch (S) to the infeed to supply outputmodules. A separate potential supply terminal EL9110 can also be used as an infeed (see followingillustration).
